Can we claim Depreciation @ 100%

Dear all, I have again a very interesting query. This is a case of a Private Limited Company. There was a super structure built in a rented premises which was vacated after 3 years (say in the month of August 2007). In earlier years, depreciation @ 10% was claimed as per Income Tax. The opening WDV is say 30 Lacs. In the books of account of the company, the asset has been written off by claimimg depreciation @ 100% and charged to the profit & loss account, which is as per the policy of the company. Now can we claim 100% depreciation in Income-tax or it is a short term capital loss after providing depreciation @ 10% for 6 Months.
